## Abstract

We consider a $(m+2)$-dimensional Einstein-Gauss-Bonnet model with the cosmological $\\Lambda$-term. We restrict the metrics to be diagonal ones and find for certain $\\Lambda = \\Lambda(m)$ class of cosmological solutions with non-exponential time dependence of two scale factors of dimensions $m \> 2$ and $1$. Any solutions from this class describes an accelerated expansion of $m$-dimensional subspace and tends asymptotically to isotropic solution with exponental dependence of scale factors.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
